Jeremiah Fink is the richest man in Columbia and the founder of Fink Manufacturing/Industries. As an inventor, he has come up with many inventions such as the Sky-hook, Kinetoscope, and Vigors. He is also the the host of the annual raffle. Throughout the game, Fink sees only the business aspect of an individual, making him a cruel taskmaster.

Booker first meets Fink in Raffle Square, which quickly ends in a fight between Booker and the Founders' police. The second meeting occurs when Booker enters Fink Manufacturing while searching for the gunsmith Chen Lin. In this meeting, Fink tries to recruit Booker to be the head of his security team, sending various enemies at Booker to test if he has what it takes.

The Other Fink: Albert and Tear Technology

Jeremiah has a brother who plays no part in the story other than one of intrigue. Albert Fink is the owner and proprietor of Fink's Magical Melodies, located in Downtown Emporia. According to the Voxophone recording found in his shop late in the game (#60: "Out of the Thin Air"), Albert has apparently been using the Lutece'sTear technology to peek through time and plagiarize songs and sounds from the future.

Albert's transgressions were apparent from nearly the very beginning of the game near Raffle Square when the floating gondola came into view bearing the barbershop quartet, The BEE Sharps, singing "God Only Knows". The song, originally by The Beach Boys in 1966, was clearly not around in 1912. Much the same for CCR's "Fortunate Son" (1969), Cyndi Lauper's "Girls Just Want to Have Fun" (1979), et al.

Murder of the Lutece Twins

While Albert Fink might only have a very minor part in the story of Infinite, the lesser-known sibling has unknowingly played a major role in the current culture and climate of Columbia. Jeremiah's discovery of Albert's use of the tears to pull in music leads the inventor to perhaps peer into the future and get insight into yet-undiscovered technologies (like the Sky-Hook, mass-production assembly lines, etc.)

As you learn in the Bank Vault while chasing the Siren ghost of Lady Comstock, Jeremiah Fink was not only an extremely busy inventor, Fink was also responsible the "death" of the chief Columbia scientists, Robert and Rosalind Lutece. Comstock asked Fink to perform the task for the same reason the Prophet had Lady Comstock killed: each now-dead party knew that Elizabeth was not Comstock's daughter true daughter, that they were only related genetically. However, when Fink attempted to kill the Luteces by using their own tear technology, rather than die, the twins came to exist across multiple realities, much as Elizabeth (by way of her pinky) and, later, Booker DeWitt.
